Normalmap with alpha tga

Hello!
I have leaf-panels for a tree, and their textur has an alpha channel, so that a part of the textur is transparent. NOW, I give the panels my normalmap shader and they lose their transparency. So my question is how should I change my code to get the transparency of the alpha channel, with normalmapping?
Please help me, this is very relevant for my game!!!
Here is the standard fx code for normalmapping(only some unimportant things were changed):
Code:

I have the same problem with my toon shader...

well the problem is you are trying to combine fixed functions with a pixel shader, this cant work because the pixel shader overrids your FF commands. Heres what you do:

get rid of the lest line in your pixel shader where it returns, and put this

Code:

---

float4 finalcolor =(0.2 * color) + ((shadow1 * (color * diff1 + (spec1)) * (1 -Attenuation1))*vecLightColor[1])+ ((shadow2 * (color * diff2 + (spec2)) * (1 -Attenuation2))*vecLightColor[2]));

finalcolor.a = color.a;	
	
if (finalcolor.a>0.5)
  {
   finalcolor.a=1;
  }
  
  else
  {
  finalcolor.a=0.0;
	} 

return finalcolor;

Thanks Matt, you get credits!
